If Joshua has to wait for the winner of Dubois / Hrgovic and if Fury doesn't bottle the Usyk fight he doesn't have a lot of decent-ranked heavyweights left. Whyte as much fun as a rematch would be ( way more fun than most of Fury's dull fights) doesn't deserve it. Parker/ AJ 2 might make sense. Keep him on his toes and stopping Parker (if he can) makes another statement and will be a decent test.
